IMPROVEMENT IN HARVESTERS.

T0 ALL WHOM IT MAY CONCERN: i p l Be it known that I, DAVID WOLF, of Lebanon, in thc county of Lebanon, and State of Pennsylvania, have* invented a new and improved Harvester; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, `in which-f,-

Figure 1 is u side sectional view of my invention, taken'in the line a', iig. Q.

l ,This invention relates tov a new and improved harvester, and it consists in a novel construetionof the platform, as hereinafter fully shown andjdescribcd, vwhereby;the cuty grain may be'readily discharged therefrom, .und kept free'from the sickle as it iscut. 4 j I 'i i Arepresents the main frame of a harvester mounted ou two wheels, D D, cach of which has a concentric;

.toothed rim, C, attached to or cast with it. D D represent t-woba-rs, one of which, D, is attached by a 'pivotbolt, (il, to the right-hand side of'thc front part ofthe main frame A, and thc rcarend connected by a pin Vor bolt, b, to one endof. the other bar D', thc opposite end of the bar D' being-attached by a pivot-bolt, c, to the left-handside of the main frame A, assshown clearly in fig. 2. E represents the cutter-bar, which has a shoe, F, attached .to its inner end. The front end vof this shoe is connected by a joint, ol, to the. bar D at'about' its centreand the rear end of thc shoe F is connected by a similar joint,'l, to a plate, G, which is attached' to.Y the bars DD( where they are connected by the pivot-bolt--Zn'said boltforming a pintlo of a hinge common to the bars D.D and to theplate G. By this arrangement the cutter-bar, and consequently the platform H, which isv attached to it, is allowed'to risc upward from the joints CZ d as centres, and the inner end of the cutter-bar is also allowed to rise, owing to a vertical movement-allowed the bars D D.- .The cutter-bar, therefore, is allowed to conform to the'inequalitics of surface over'which. it maypass, and by withdrawing the bolt of the joint d, the cutter-bar may, when the whole of the platform is not attached, be turned around to the rear of the main frame A, and suspended therefrom, where it will be out of the way, and the deviccrend'ered. convenient for moving from place to place. The platform is ajointed one, composed of three parts, e c connected by: joints or hinges,f, and the front part e has a bent arm, g, secured to one end of it, von which a rod, I, is fitted, the front end of said rodbeing fitted on an upright arm, k, at one end of a shaft, J, which is placed in lthe front part ofthe main frame A, and has a'. stirrup or foot-piece, K, scoured upon it. By actuating the shaft J through the medium of thefoot-piece K, the jointed platform may be A moved so as to discharge the cut grain therefrom, the cut grain falling upon the platform, when the front joint .or hinge f is depressed, and whenever said joint or hinge is' raised the cut grain will be discharged from the platform, the partsL in this operation being removed from the platform. In case it is desired to rake the eut grain from the platform a supplemental part, L, is attached to the rear part el of the platform H, said part having an upright flange, t', attached to hold the grain on L, and admit of a person raking the eut grain therefrom. This supplemental part L of the platform rests upon a bent arm, M, -attached to the shoe F. A lever, N, is attached to the shoe F to admit of the driver raising the outer end of the cutter-bar and platform whenever required. O is the shaft, from which the sickle is driven. This shaft is fitted in proper bearings in the main frame A, and it is provided with a collar, j, near each end; and having upon it, adjoining the collar, teeth 7c, as shown clearly in fig. 6. y On the outer ends of the shaft -O there-are tted pinions I which are recessed, or have cavities Z made in them, with elastic pawls m to catchV against the teeth 7c, when the machine is moving in a forward direction, and thereby rotate the shaft O. The pinions are rotated bythe geared or toothed rims C C. In backing the machinethepawls m slip over the teeth c. By this arrangementthe pawls and teeth are preserved from all dust, as they are completely. enclosed. The pinions, it will be seen, are simply .fitted loosely on the shaft O, and they can be removed with the greatest facility, and reversed on the'shaft O, that is to say, the pinion on one end of the shaft, which .rotates the shaft' when the machine is moving in a, forward direction, may he taken off and applied t0 the opposite end of said shaft witheut rotating the sume when the machine is moving in a forward direction. By thus shifting the pinions P the machine may be drawn from `place to place, with communicating motion to the sickledmr. A bevel-wheel is to be secured on shaft O, meshing with another bevel on :L shaft bearing the crank, by which motion can he communicated te the sickle.

Haring thus described my inventionfwlmt I claim :is new, and desire to secure by Letters Patent, is-

The Hanged extension part L. in combination with the hinged-jointed platform H, substantially as and for the purpose dewribed.A
